[Iceman]

The Ultimate Universe Magneto was the unflinching evil badass.

It makes sense to me that Magneto would chill over the years with all that's happened. His powers weakening and then going away for a time. I think M Day really changed a lot. When you go from millions of mutants spread around the planet to less than 1,000 you have to change your thinking. If he wanted to kill all humans they wouldn't have enough to repopulate anyway. Scott keep things together for the entire mutant population when they were very close to being killed off. Magneto was either dead or powerless most of that time, otherwise I do think he would have been involved.

But hey, I was always the person that wanted to see Xaiver and Magneto working together on some middle ground.
